[pct-l] Insoles for road walks?

[Chris Martin]

Hi PCT-L,

Like many hikers, I wear lightweight trail shoes with minimal cushioning
(New Balance MT101). These depend on some 'give' in the trail surface for
cushioning one's feet, which means uncomfortable (and eventually injurious)
shock loading when walking on hard asphalt with a 20-pound pack.

I'd assume that some insoles with cushioning would solve this. What have
you had success with? Something that is antimicrobial and nonabsorbent
would be ideal.

Thank you,

Chris
